PRESS.

SPECIFICATION forming part of Letters Patent No. 319,185, dated June 2, 1885.

Application filed March '25, 1885. (No model.)

To rtZZ whom it may concern.-

Beit known that I, Burns E. Bosonnnr, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Presses, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to platforms which are arranged to traverse across the pressbed and have a capacity of carrying 2. tier of cheeses at each end, so that the pomace may be placed upon one end of the platform,while that upon the opposite end of the plat-form is under the follower to receive the pressure of the press.

The invention has also reference to that class of reversible platforms which are pivoted at or near one end of the press-bed.

The object of the invention is to simplify the construction of the platform so as to admit of a ready application of the same to a press, and also to render said platform strong, durable, convenient, and efficient inits operation.

In the accompanying drawings, Figure l is a front elevation of a press provided with my improvements. Fig. 2 is a plan view of the same, and Fig. 3 is an inverted plan view of the platform.

Similar letters of reference indicate corre sponding parts.

A represents the bed or foot block of an upright press,which foot-block is connected with the head-bl0ck B by tie-rods B R, the press ing mechanism being interposed between said foot-block and head-block to exert the pressure against the head-block and the substance placed between the follower F and foot-block or press-bed.

T represents a circular track arranged around one end of the press-bed or foot-block A, the center of the circle formed by the track being located outside of the tie-rods R R, as shown at a in Fig. 2 of the drawings. This circular track is composed of a section which terminates at opposite sides of the press-bed, and is secured stationary to the floor, and a segmental section, which extends across the press-bed, is attached thereto so as to be carried thereby and raise and lower with it during the operation of the press, the raising of the press-bed, and in fact of the entire press, being due to the following facts: When the platform is turned to bring the pomace under the follower and before the latter is brought to bear on the pomace, the press rests on the floor, and the tracksection of the press-bed is even with that part of the track which is supported on the floor and is stationary. The platform being supported by its rollers r r on the stationary part of the track at opposite sides of the press leaves the platform without any bearing on the press-bed. In bringing the follower to press on the pomace the toggle-levers which operate the follower exert an upward pressure on the head-block B and a downward pressure on the platform, which latter transmits the pressure to the stationary track supporting the platform, as aforesaid. As the pressure increases the resistance of the stationary track causes the toggle-levers to push upward against the head-block,a11d inasmuch as the latter is connected with the footblock or "pressbed by the rods R R, and the press-bed is clear of the platform and free from pressure, the entire press is lifted by the resistance of the stationary track supporting the platform. The pomace thus receives only the weight of the press until the press-bed is drawn up against the under side of the platform, as illustrated in Fig. 1 of the drawings. After that the downward pressure is resisted by the press-bed, and the pomace receives the full effect of the press. When the pressure is relaxed and the follower raised,the press-bed descends again to the floor, and then the tracksection which is mounted on the press-bed is in position to allow the rollers of the platform to traverse it.

1? denotes the duplex platform,which has a capacity of carrying two tiers of pomace or cheeses at opposite sides of the center of its length, as represented in Fig. 1 of the drawings. Beams or planks O O are secured across the under side of the platform for the purpose of stiffening the same and preventing its deflection when loaded with pomace. This platform I pivot at its center on a gudgeon or stud-pin, a, secured to the end of the pressbed at a point coinciding with the center of the circle described by the stationary track T, the pivotal connection of the platform being made by a plank or beam, b, secured to the under side of the platform in such a position as to prevent its collision with the tie-rods R B when swinging the platform to carry opposite ends thereof alternately over the pressbed, said beam 1) being provided with an eye into which the gudgeon a projects.

An aperture, 0, of proper size is made in the platform to allow the same to turn freely about the two tie-rods It R near the pivot a.

r 1' denote rollers interposed between the platform P and track T, and preferably journaled in brackets or suitable bearings, d (Z, attached to the under side of the platform directly over the stationary track upon which said rollers travel.

The platform is designed to be turned alternately in opposite directions in carrying the ends thereof successively over the press-bed, and in order to arrest the rotation of the platform at a proper time to bring the tier of pomace into the requisite position to receive the pressure of the follower F, Iprovide the platform with stops 6 e, consisting of projections on the ends of the platform, which projections collide with the tie-rods R R at the end of the press opposite the end on which the platform is pivoted.

The platform is provided with a flange or ledge around its edge and around the opening 0 to prevent the escape of the expressed substance thereat.

Underneath the platform is placed a receptacle,f, for the drainage of aforesaid expressed substance, which is conducted thereto by a hose or flexible conduit, g, connected with a discharge-opening, h, in the platform 1), and having its free end in the receptacle f, the flexibility of the conduit allowing it to accommodate itself to the changes of its position in relation to the receptacle during the revolution of the platform.

Having described my invention,what I claim as new, and. desire to secure by Letters Patent, is

1. The combination, with the press, of a circular track arranged around a center located at one end of the press-bed, said track being composed of a section terminating at opposite sides of the press-bed, and secured stationary to the floor, and a segmental section secured to and carried by the press-bed, a ducular track arranged stationary around one end of the press-bed and extending across the central portion of the same, the platform pivoted at its center to the end of the press, rollers underneath the platform, and stops arranged to arrest the rotation of the platform in bringing alternately opposite ends of the platform over the press-bed, substantially as set forth.

3. In combination with the press having vertical tie-rods at opposite ends, and the circular track arranged around one end of the press-bed, the platform pivoted at its center to one end of the press-bed and provided at its two ends with projections adapted to collide with the tie-rods at the opposite end of the press-bed during the rotation of the plat form,substantially as described and shown, for the purpose set forth.

4. In combination with the circular track, press-bed, and gudgeon a on one end of said press-bed, the platform formed with the apertures c,and the plank or beam b,secured to the platform, and provided with an eye by which the platform is pivoted on the gudgeon a, substantially as described and shown.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 21st day of March, 1885.
